Data Logging

Yay It's finished. Today I finished the temperature sensor programming today. Then I thought that I should try it and Alex helped me. We got a cup of water straight out of the tap and then pressed the button to start the data logging. I didn't think that It would be very hot, but it was about from 15-25 degrees celsius. I tried it on my arm and it got to about 31 degrees. Next week I'm going to try making a speed logging one. I'm not too sure what it does though.

How hot is the water?

Temperature sensor

Robots are so difficult to program. I've carried on programing the NXT Lego mindstorm. I've tried it two years ago so I sort of have an idea on how to use them but I still use the guides on the app that we use to program them. There are lots of different sensors that you have to make to put on the Rem bot. I made one which was the light sensor. Which I then programmed it to follow a black line. It took about five minutes, then you just click the download button and it downloads to the NXT. I don't think that we've used the temperature sensor on the robots before so I thought that I would try it. I've started to program the robot to tell me how hot a cup of water is. (I think) I Haven't finished because it has about 83 steps to follow, but I will finish it next week.

Digital Citizenship

This afternoon we were put into groups and then went off to talk about digital citizenship. It's about realising the implications when you are using Facebook, Twitter and Flicker. First Nicola gave us a sheet that had the names of all of a person's friends and had lots of connecting lines to show that somehow they all connected. After we had talked about that we were given another two sheets that asked us questions like how often do we use technology at home and do our parents know what we're doing on the computer. Once we had filled out the sheet Nicola called us over to her to watch a video. It was talking about how everybody knew the girl's name just from the internet. The video above is the last video that we watched. It talks about your digital dossier which starts just before you're born and then just grows and grows.
